GENERAL SITUATION Soil moisture conditions are wet. Rainfall was recorded on May 3-5 with totals ranging from 1.25-over 5 inches. The majority of the area received 2-3 inches. Corn and grain sorghum has made good progress since t he rainfall. Cotton growth stage will range from just starting to come up to 4 true leaves. The oldest and most advanced cotton will begin to square next week. CORN and GRAIN SORGHUM Chinch bugs have been seen in some area corn fields over the past few weeks. The recent rainfall should aid in reducing damage from this pest. Greenbugs are being seen in light numbers in grain sorghum. Corn leaf aphids are in light to medium numbers in the whorls of milo. This insect does not inject a toxin into the plant and is also a good source of food for beneficial insects. COTTON Producers should continue to monitor any cotton planted in weedier conditions for cutworms and armyworms. (Armyworms, in general, are in light numbers.) Thrips numbers and damage are very light. Cotton aphids are in light numbers. Grasshoppers have been seen in area pastures over the past several weeks. The numbers appear to be consistent to what we have seen over the past few years. Overwintered boll weevil trap counts are light numbers |

*********************************************** Producers with Roundup-Ready cotton should monitor their fields closely for plant growth stage and time the Roundup application prior to the 5th true leaf reaching the size of a quarter. Farmers should anticipate adverse weather (wind or rainfall) and apply this application early enough to insure plants have not exceeded the recommended size. Warmer temperatures have accelerated plant growth. Cotton is growing-off quicker than expected. ********************************************** Beet
armyworm are being seen in light numbers.
BEET ARMYWORM TRAP COUNT
(The cumulative average of two traps/week. Trap location is in the Chatt area.) *********************************************** EPA has approved a FIFRA Section 18 exemption request which allows for Denim use to control beet armyworms on cotton in Texas. All documents dealing with the Section 18 must be in possession of the applicator at the time of application. This means that all conditions as outlined in the document must be followed. Progress is being made by Syngenta Crop Protection toward full labeling of Denim. **********************************************

*********************************************** The Environmental Protection Agency (EPA) has approved a Section 18 exemption as requested by the Texas Department of Agriculture (TDA) for the use of Furadan 4F to control cotton aphids in the state. The document may be obtained from the TDA website at www.agr.state.tx.us/pesticide/18crops.htm. Copies of the Section 18 documents must be in the hands of the operator before Furadan can be applied to any cotton field for aphid control and all requirements followed. Once cotton aphids reach the threshold levels defined in the Section 18 document, Furadan 4F may be used. **********************************************
